I wrote a custom assembly to assist my with my data access. I want to be able to use the methods exposed by this assembly in a separate custom control I wrote that displays a dropdown list based on some fields in a DB. This is a 'uses a' relationship but I don't know how to allow the control to inherit the functionality of my data object. When I add the line:<BR><BR>using MyDataObject;<BR><BR>it returns an error at compile time. 'Cannot find this reference' or something of the like. How do I allow my controls to use eachother in the same way that any of my controls can inherit the functionality exposed by the .NET framework?<BR><BR>Note: <BR><BR>1.) the assemblies have all been placed in the /bin folder/<BR>2.) all files are written or maked up in csharp, a text editor.<BR>3.) Visual Studio is not at my disposal.<BR>4.) The assembly that controls data access works when imported to a regular csharp page.<BR><BR><BR>Thanks in advance!
